Abstract: PURPOSE: To improve lubricating performance so as to suppress the wear of a thrust pad to a low degree and thereby to prolong the service life by supporting the end part of a rotary shaft with the protruding end part in a thrust direction by an oil impregnated bearing. CONSTITUTION: When the tip part 27 of a shaft 19 is rotated, the initial surface of a thrust pad 28 is a plane, but the surface of the thrust pad 28 is changed into recessed shape by the contact sliding with the tip part 27 of the shaft 19 and the elastic deformation. An operating clearance exists between a sliding bearing 24 and the shaft 19, so that the shaft 19 is rotated eccentrically from the center O1 of the sliding bearing 24. At this time, a positive pressure part PP and a negative pressure part NP are generated in the vicinity of a contact point 31 between the thrust pad 28 and the spherical surface 31a of the tip part 27 of the shaft 19 on the basis of hydrodynamic wedge film action.  Since oil impregnated sintered metal is used for the thrust pad 28, oil leaches from the oil impregnated sintered metal due to negative pressure generated by the eccentric rotation of the shaft 19, and an oil film is always formed between the thrust pad 28 and the tip part 27 of the shaft 19 so as to improve lubricating performance between the thrust pad 28 and the tip part 27 of the shaft 19.

Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent damages to a connector lead at connector mountingdemounting by providing a casing, which has a regulating wall for regulating the movement of a connector through external force acting on this connector by mounting/demounting of an external connector which makes a pair with the connector. SOLUTION: In a connector-mounting structural body 1, a connector 10 is fitted and fixed to a housing 20 to fix a printed wiring board 40. As a result, the movement of the connector 10 by the action of external force by mounting/ demounting of an external connector, is regulated by the housing 20 and a cover body 30. For example, a movement of the connector 10 in the direction shown by an arrow K is regulated through an opening peripheral edge part 20a of the housing 20. Consequently, a connector lead 12 can be prevented from being damaged by external force through the mounting/demounting of the external connector. Reduction in element mounting density can be prevented by reducing an element unmountable area on the printed wiring board 40 through the dispensing of the necessity of placing the connector 10 on the printed wiring board 40.
